STEAM-TRAP.

To all whom it may concern:

Be it known that I, FRANZ ABELs, a subject of the German Emperor, andresident of Bremen, Germany, have invented certain new and usefulImprovements in Steam- Traps, of which the following is a specification.

The present invention relates to a steam trap designed to be applied toany apparatus in which steam is used as a heating means, and whichcomprises a tubular casing with in which the cooled, water loaded steamflowing back from the heatin apparatus, passes through a plurality 0superposed ducts formed by nearly annular grooves provided in theperiphery of a central core which tightly fits the tubular receptacle.Said ducts or grooves are not Wholly circular, as a rib, extendinglongitudinally from one end to the other of said core is left, so thateach groove separately is provided with a bafiie, said bafiles being ofcourse superposed all along the core, Each of said grooves is connectedwith the following one by means of a notch provided in the annularprojection left between two superposed grooves, said notches beingadjacent to the longitudinal rib and alternately disposed at the leftand at the right hand of said rib. At top of said core and fitting saidtubular casing is a movable steam regulating disk provided with anadjustable hole corresponding to the uppermost one of the abovedescribed notches and through which the watery steam enters the firstgroove in one direction flows through said groove, breaks against therib which acts as a baflle, enters the following duct through theadjacent connecting notch, flows through said last duct in an oppositedirection with respect to the foregoing one, breaks against the baffleof said duct, enters the'following duct and so on through the wholedevice until it escapes at the lower end. By these means the steam isquickly condensed.

In the accompanying drawings Figure 1 is a side elevation partially insection of the steam trap. Fig. 2 is a top plan view of the core, thecasing being in section. Fig. 3 is a bottom plan view of the core, thecasing being in section. Fig. 4 is a view similar to Fig. 1, butillustrating the flanges of the core arranged at an angle.

In Figs. 13 Z) is a central core which Specification of Letters Patent.

snugly fits in an annular casing a into which flows the steam from aheating apparatus. Integrally formed on the periphery of sald core arespaced apart annular flanges, the spaces forming grooves d. Said groovescl do not extend entirely around the core, a rib 9 being left all alongthe core. A movable disk It provided on top of said core 6, and providedwith an adjustable hole 29 serves for regulating the jet of steamentering the trap. In the solid portions between the grooves 03 notches0 are provided alternately at the left and at the right hand of the ribg, each of said notchesconnecting two superposed grooves. The steamflowing back from the heating apparatus enters the .hole p of theregulating disk It, flows through the upper groove al, in the directionof the arrow 9, and breaks against the corresponding portion of the ribg which acts as a baflie, enters the notch 0 at the right hand of saidrib and then in the following groove d where it flows in the directionof the second arrow r, that is to say in an opposite direction withrespect to the foregoing one, breaks against the corresponding battleand so on until it escapes at the lower end of the separator, where thecondensed water leaves the steam through a special duct.

In Fig. a the grooves (2 instead of being constructively disposed withrespect to the axis of the core as in Fig. 1, are helical.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent, is:

A steam trap comprising a casing, an inlet pipe at the top of thecasing, an outlet pipe at the bottom of the casing, a core mounted inthe casing between the inlet and outlet pipes, said core having anintegral radial rib which abuts against the inner wall of the casing, aplurality of spaced apart flanges, all of the same size and which areintegral with and extend from the core to the inner wall of the casing,part of said plurality of flanges extending from the left side wall ofthe rib and terminating some distance from the right side wall of saidrib to form exit openings, the remaining part of the plurality offlanges being in terposed between the first mentioned part of saidplurality of flanges and extend from the right side wall of the rib andterminate some distance from the left side Wall of said control the flowof steam entering the cirrib to form exit openings, the exit openingscuitous passage. 10 formed between the terminals of the flanges Intestimony whereof I have hereunto set and the side Walls of the ribbeing altermy hand in presence of tWo Witnesses.
